STEAM-TRAP.

SPECIFICATION forming part of Letters Patent No. 758,725, dated May 3,1904. Application filed January 18,1904. Serial No. 189,402. (No model.)

To aZZ whom it may concern:

Be it known that I, HENRY J. \VEssINeER. a citizen of the UnitedStates,residing at Duluth, in the county of St. Louis and State ofMinnesota, have invented certain new and useful Improvements inSteam-Traps; andl do hereby declare the following to be a full, clear,and exact description of the invention, such as will enable othersskilled in the art to which it appertains to make and use the same.

My invention relates to steam-traps, and has for its object theprovision of a trap in which the various parts are easily accessible forcleaning or repair.

WVith this and other objects in view it consists of a casing providedwith a suitable head or cover, a tilting bucket mounted within saidcasing, and valves mounted in said head.

It also consists of certain other constructions, combinations, andarrangements of parts, as will be hereinafter described and claimed.

in the drawings, Figure 1 is a central vertical section through my saidinvention. Fig. 2 is a bottom plan View of one of the valves thereof.Fig. 3 is a top plan view of the cover forming part of said invention,and Fig. at is an elevation of an assembling-tool.

In the drawings, 1 is a casing provided with a cover 2. Pivotallymounted within said casing, as at 3, is a tilting bucket el, provided atits upper forward edge with a -lip 5, adapted when said bucket is raisedto bear against a stop 6, formed upon the inner wall of said casing. Thecasing is further provided near its upper edge with an inlet-port 7 anda discharge-p0rt-8 and near its lower edge with a blow-oif ordrainage-port 9. A deflecting-lug 10 extends from the wall across saidpoi-t7. On said cover is formed a housing 11, containing twovalve-chambers 12 and 13, respectively. The lower end of said chamber 11normally communicates with the upper end of the chamber 12 by means of aport 14, formed in said cover. Said chamber 12 is open at its lower endinto the bucket chamber or reservoir 15, and the upper end of saidchamber 12 is closed by a plug 16. The valve-chamber 13 isdiametricallyreduced intermediate of its ends by a contraction of itswalls, as at 17, and below said contraction communicates with a passage18, which in turn communicates with said discharge-port 8. The lower endof said valve-chamber 13 is closed by a vertically-apcrturcd plug 19,adapted to form a seat for a valve 21, positioned in said chamber andreduced at its lower end, as at 21 and 21". A pipe 22 is secured at itsupper end to said plug 19 and communicates with the aperture therein andextends downwardly into said bucket and nearly to the bottom thereof.Positioned within said chamber 12 is a balanced valve 23, diametricallyreduced intermediate of its ends, as at 2%, and centrally apertured, asat 25. Depending from said valve are one or two transversely-aperturedlugs 26, to which is pivotally secured the upper end of a link 27, whichlink is pivotally secured at its lower end to one or twotransverscly-apertured lugs 28, extending upward from the bottom of saidbucket. The upper end of the aperture in said valve 23 is preferablythreaded to engage a suspending-rod 29, which may be used in drawingsaid valve 23 into said chamber 12 when assembling the parts of saidinvention, the rod 29 being removed after said valve is in position.Said chamber 12 from a point above and near the mouth of said port 1%communicates, through a port 30, (extending through a shoulder 31,formed on said housing,) with the passage 18, near said discharge-port8. It will be observed that communication between said port 30 and saidport 1% is normally cut off by the lower end of said valve 23, but thatwhen said valve 23 is drawn downward by said bucket and link the port 14will communicate with the port 30 through the passage or groove formedby the reduced portion of said valve. The upper end of said chamber 13is closed by a plug 31, upon the inner end of which is formed adepending stop 31. The ports 7, 8, and 9 are internally threaded toreceive pipes 7, 8, and 9, respectively. Said pipes 7 and 9 arepreferably provided intermediate of their ends with cut-off valves (notshown) of any suitable construction for the purpose of arbitrarilyclosing said pipes when not desired for use, said valves being wellknown to the art and not thought necessary to be shown or particularlydescribed herein.

Inoperation the chamber 15 is preferably partly filled with waterthrough an aperture in said casing or cover, which is then closed by aplug 32. Steam and water then enter said trap through. the port 7 thewater being deflected down by said lug 10 and collecting in the chamber15. The steam circulates freely in said chamber 15 and passes throughthe aperture in the valve 23 to the chamber above the same and alsothrough the port 14 to the chamber above the valve 17, at the same timepressing upon the lower end of said valve 23 and also entering throughthe pipe 22 and pressing against the reduced end of said valve 21. Thewater collecting in the chamber 15 will eventually rise around saidbucket and flow over the top of the same, filling said bucket andtilting it down, in which movement the bucket will draw down the valve23. As the reduced portion of the latter valve passes the mouth of theport 14 the steam will escape from above the valve 17 through the port14 and the passage around said reduced portion 24 and through thepassage 30- and 18 and through the port 8, this relieving the pressureabove said valve 17, which is thereupon lifted by the water forcedupward in said pipe 22 by the steam-pressure above the water in thebucket. Said water then'escapes under steam-pressure through the passage18 and port 8 until said bucket is substantially emptied, whereupon thebucket is raised or floated again by the water surrounding it. The valve23 simultaneously rises, uncovering the port 14, and steam passes to thechamber above the valve 17 thus closing said valve. It should beobserved that said valve 23, after establishing communication betweenthe passage 30 and the port 14, continues to descend until the passage30 is again closed by the upper end of said valve.

Having now described my invention, what I claim, and desire to secure byLetters Patent, is

1. In a steam-trap, the combination of a reservoir provided with aninlet-port, a clownwardly-tiltable bucket positioned in said reservoir,a cover for said reservor having suitable valve-chambers and suitableports formed therein, a balanced valve positioned in one of saidchambers and adapted to govern some of said ports and connected withsaid bucket by a connecting link or rod pivoted at one end to said valveand pivotally connected at the opposite end to said bucket, and a valvepositioned in the other of said chambers and adapted to govern anotherof said ports, substantially as described.
